New status effect: Weak

This is in essence an anti-might: a reduction in the actor's melee damage
output while the effect lasts.

Currently it reduces monster melee damage by 33% (exactly cancelling out
monster might), and player melee damage by 25%. This is not the inverse of
player might, but I feared a subtractive reduction might be both too harsh
early on while too ignorable later on. Quite possibly the numbers will need
adjusting after playtesting.

One potential concern is that its name overlaps somewhat with the internal
naming for death from strength loss (ie: DEATH_BY_WEAKNESS), but I am not
sure that it is ever displayed to the player by that name? (The status light
is Collapsing, after all). If someone objects and has a better name to offer,
be my guest.

Elyvilon's Purification ability will remove weakness, though currently this
is the only way to do so, aside from waiting it out.
